Title: Add autodividers functionality for listviews

Can be used to autogenerate dividers for a listview by
setting data-autodividers="alpha" (dividers are unique,
uppercased single characters from list items) or
data-autodividers="full" (unique full text strings selected
from list items) on the ul element of the listview.

It's also possible to apply a custom selector to find the
elements to be used for divider text, with
data-autodividers-selector="...".

This relates to https://github.com/jquery/jquery-mobile/pull/2466,
but is a different implementation which will automatically
update the list dividers if the list elements change. It also
has a fairly thorough test suite and documentation.
